GRADING AND DITCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 759,606, dated May 10, 1904.

Application filed January 14;, 1904. Serial No. 189,032, (No model.)

TO (1157/ 107mm 11/; WHY/y 001106771: elevating-carrier, an illustration of a machine Be it known that I, THoMAs J. GRAY, a citiof such general character being, for examzen of the United States, residing at Chicago, ple, found in Letters Patent No. 275,614, in the county of Cook and State of Illinois, April 10, 1883, to Edwards and Durkee. In 5 have invented certain new and useful Improvesaid patent the elevating-carrier comprises two ments in Grading and Ditching Machines, of main lengths or sections, one being arranged which the following is a specification. under the body-frame and commonly termed My invention relates to grading and ditchthe bed-frame and the other being hinged ing machines involving a carriage, an elcvatat one side of the body-frame to a pair of IO ing-carrier, and a plow from which the loose standards and commonly termed the carriersoil is taken by the elevating-carrier and disframe. These sections or lengths of the elecharged thereby at a suitably-elevated point. vating carrier are provided with belt-rolls Objects of my invention are to avoid such for an endless carrier-belt, means being also an extent of separation between the bed-frame provided for swinging the outer or carrier- 6 5 and the carrier-frame as will injure the belt frame section independently of the bed-frame when the carrier-frame is swung upwardly, to section, so that when desired the former can materially lessen the extent or certain conbeswung into asubstantiallyupright position. nections between the two frame-sections when In the accompanying drawings, portions one of them is swung in a vertical plane indeonly of the lower bed-frame section B and the 6 5 2O pendently of the other, to positively adjust outer or upper carrier-section C of the elevat: the length of the elevating-carrier as a whole ing-carrier are illustrated, it being considered without interfering with the proper action of a unnecessary to further illustrate the machine hinge device for the carrier-frame section, to to which my improvements are applied. The longitudinally adjust the carrier-frame secelevating-carrier, as in preceding machines of 5 tion without tilting it, and to provide novel this class, is also provided with an endless earand improved means for hinging and supportrier-belt D. It is also understood that as in ing the'carrier-i'rame section. such prior machines the bed-frame section B In the accompanying drawings, Figure 1 is in practice positioned under the body-frame represents in side elevation a portion of the and arranged to extend upwardly from the 3 body frame of the machine and portion of the plow and that the swinging carrier frame upper and lower elevating-carrier sections arlength or section C, which practically forms a ranged and supported in accordance with my continuation of the bed-frame B, extends upimprovement. Fig. 2 is a View similar to wardly and outwardly from one side of the Fig. 1, but showing the upper elevating-carmachine substantially as in the said Edwards 8 35 rier section adjusted longitudinally in a diand Durkee patent.

rection away from the, lower section, so as to As the elevating-carrier involves like suscompensate for stretch on the part of the endpending and hinging devices at each of its less belt. Fig. 3 is a side elevation generally two longitudinal sides, the following descripcorresponding with prior figures, but showing tion "of the suspending and hinging devices 5 4 the upper elevating-carrier section swung upshown at .one side, as in Figs. 1, 2, and 3, will wardly to an extent to place it in an upright also practically serve as a description of the or nearly vertical position. Fig. 4: is a top corresponding suspending and hing-ing doplan view of Fig. .1. vices at the opposite side, it being apparent The standards A A represent portions of the that the duplication of these devices is suiii- 9 45 body-frameoi' agrading and ditchingmachine ciently illustrated in Fig. 4 to serve as a having a plow and a transversely-arranged guide for the general arrangement involved.

-With particular reference, therefore, to the suspending and hinging devices shown at one side of the elevating-carrier, E indicates a plate or bar secured to one side of the carrierframe section C, and therefore practically forming a portion of such frame-section. A suspending-link F for the inner lower end of the carrier-frame section is pivoted at its lower end, as at 1, to the carrier-frame section, preferably to the bar or plate E, as shown, said link being hung at its upper end upon a fixture G on the body-frame.

The fixture G is shown as being a bar or plate secured to the standard A and provided with a series of bolt or pivot holes 2, arranged along the arc of a circle. The bolt or pivot 3, by which the link F is suspended, can be fitted to bear in any one of these holes 2, and hence the point at which the link is pivotally hung can be raised or lowered along the line of an are by shifting the bolt 3 from one to another of such holes. Broadly considered, therefore, the point at which the suspension-link is hung can be adjusted up and down along the arc of a circle. It is understood that the circle thus referred to has its center at or near the lower end of the bedframe B just back of the plow, so that when the axis of the hinge is thus raised or lowered, so as to raise or lower the elevatingcarrier, the proper relative position between the plow and the bed-frame B will be maintained.

While the bar or plate forming the fixture G may be of any desired form, it is shown as practically forming a quadrant. The bolt 3 also provides a pivot for a link H, which connects the body-frame with the carrier-frame section G, the link H being considerably longer than the suspension-link F and having its outer lower end pivoted to the carrierframe section-for example, to plate E-by means of a pivot 4E. The pivot 4 is adjustable along the carrier-frame section for the purpose of longitudinally extending or contracting the elevating-carrier with reference to the condition of the belt D and its requirements. To such end the bar or plate E is provided with a series of bolt or pivot holes 5 for the bolt or pivot 4, whereby the adjustment of the latter along the carrier can be effected.

In Fig. 2 the pivotal connection between link H and the carrier-frame section is adjusted so as to lengthen the elevating-carrier relatively to its condition shown in Fig. 1, it being observed that in the condition shown in Fig. 1 the suspension-link F is nearly vertical, while in Fig. 2 it inclines back toward the body-frame as a result of such adjustment, which serves to project the outer carrier-frame' section in a direction away from the bod-frame in order to lengthen the elevating-carrier as a whole.

a slide-bar I, which is guided by any suitable guide or guides 6, and arranged with its outer end pivoted to the suspension-link F at a point between the two pivoted ends of such link, as at 7, Fig. 2. When the suspension-link F is swung from the position shown in Fig. l to the position shown in Fig. 2 by reason of the projection of the carrier-frame section, the bar I will slide outwardly to an extent determined by the extent of such projection, it being observed, however, that as the pivotal connection between barI and the suspensionlink is between the ends of the latter the extent of outward movement on the part of bar I will be less than the outward movement of the lower end of the suspension-link,which is pivoted to the outer carrier-section.

WV hen desired, the carrier-frame section C can be swung upwardly, as in Fig. 3, and in such case, while the suspension link will swing upwardly, as illustrated, the forwardsliding movement of bar I will still be comparatively slight by reason of its hereinbeforedescribed connection with the suspensionlink.

The suspension-link F thus arranged provides a swinging fulcrum, the slide-bar I being pivoted to such link in place of being pivoted directly to the carrier-frame section and the said link F being in turn pivotally sup ported upon the body-frame.

The devices thus illustrated at one side of the elevating-carrier are duplicated at the opposite side thereof and are therefore, so far as visible in Fig. 4, indicated by reference letters and numerals corresponding with those of the first three figures.

What I claim as my invention is 1. In a grading and ditching machine, the elevating-carrier comprising a bed-frame section and a carrier-frame section; swinging suspension-links supported upon the bodyframe of the machine and pivoted to the inner end portion of the carrier-frame section; and links having pivotal connections with the carrier-frame section arranged for adjustment along the latter, said links and also the said suspending-links being hung to swing about an upwardly and downwardly adjustable axis.

2. In a grading and ditching machine, the elevating-carrier provided with suspensionlinks which are hung to swing upon the bodyframe about a pivotal connection therewith which is adjustable up and down along the arc of a circle such as described.

3. In a grading and ditching machine, the elevating-carrier comprising a bed-frame and a carrier-frame, and provided with suspension-links which are hung upon the bodyframe; and slide-bars connected with the bedframe and having pivotal connection with the suspension-links between the pivoted ends of the latter.

4;. In a grading and ditching machine, the body-frame and attached to the carrier-frame elevatlng-carner comprlsing a bed-frame and by plvotal connectlon ad ustable along such a earner-frame; suspenslon-hnks hung for up frame.
